Most cases of angioedema are histaminergic, often linked to chronic urticaria. Angioedema occurrence in chronic urticaria isn't a severity indicator but suggests a longer disease duration.
Area of Science:
- Immunology
- Dermatology
- Allergy
Context:
- Angioedema is frequently histaminergic, presenting as deep swelling, and recurrent episodes can lead to a chronic urticaria diagnosis.
- Chronic urticaria, while benign, is autoimmune in 40% of cases and can manifest with angioedema.
- Angioedema in chronic urticaria is not indicative of disease severity but is associated with a prolonged disease course.
Purpose:
- To clarify the relationship between angioedema and chronic urticaria.
- To inform clinical assessment and management strategies for patients with chronic urticaria and angioedema.
Summary:
- Histaminergic angioedema is common and can be the sole manifestation leading to a chronic urticaria diagnosis.
- The presence of angioedema in chronic urticaria correlates with longer disease duration, not severity.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) and systemic corticosteroids are identified triggers for angioedema in this context.
Impact:
- Highlights that angioedema in chronic urticaria does not necessitate further investigation if the patient responds well to antihistamines.
- Emphasizes the benign nature of chronic urticaria, even when angioedema is present.
- Provides clarity on the prognostic implications of angioedema in chronic urticaria.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
